 Nov 14 answered Drawing a large set of Graphics3D cylinders provided a set of cylinder specifications in a list Nov 13 comment Partitioning a list of numbers the Mathematica way This so much memory efficient. Tested BinList with f = Union@RandomInteger[{-10^7, 10^7}, 10^5]; v = Sort@RandomInteger[{-10^8, 10^8}, 10^7]; on a 64GB system and MMA9 aborted. Yours worked fine and took mere 56 sec..+1 Nov 12 comment Partitioning a list of numbers the Mathematica way This is much faster than other methods too! +1 Nov 12 answered Partitioning a list of numbers the Mathematica way Nov 10 comment ListPlot3D of a set of points in a non-convex region @rm-rf For a arbitrary point cloud on an unstructured grid we will have to accept the Interpolation::udeg message too! Interpolationorder will be constrained to one.
